To all .whom it may concern:

'Be it known that I, ANDREW EPPLER, a citizen of the United States,residing at Lynn, in the county of Essex` and' Stateof Massachusetts,V-have invented certain new and useful Improvements in Thread- WaxingDevices-g and-I do -hereby declare the following to be a full, clear,and exa/ct description of the invention, such as lable others skilled inthe art to whi it appertains to make and 'use thesame.

,. The present invention relates .t thread waxing devices. for use fonwaXth/iead-Sewing machines- One of the objects of the vpre'sentirwen-vtion is lto produce a thread-Waxing device readily Vhad vt0 the' device*gr having improved means forI heating the scribed 'and .claimed theadvantages of which will be obvious to /those skilled inthe art from thefollowing ,description/ The several 'features/ of the pre/sent ,ins

vention will be clearly understood from an inspection Aof 'vvhichlFigure 1 -is a transverse section of a thread waxing device ebodying thesev- 'the accompanying drawing in eral features of the present.invention intheir preferred form, I,and Fig. 2 is a view in sideelevation partly in' section, of the.,

Winged nuts 5 arethreaded upon the upper v ends ofthe bolts Vand are`arranged to bearY pipe 9'is providedmzhich passesvertically" downwardin' a straight line completely through the pot. At-.its upper end thepipe 9 is connected to a1 supply pipe 10 'and at,l its lower end to avsupply, pipe 11. 9 being straight presents no bends or pockets tocollect water 'of condensation and lalso The pipe f oil'ers noobstruct-ion to the upwardan-d downward movements/ofthe wax pot. The

piper is completely .surrounded .by 'the warg' and eXtends/'parallel/andvin closeproX1m1ty\ to the thread 6 so that it act/sin/an efficientvmanner to melt the wax in/' proximity yto thethread. This arrangement ofthe steam pipe also avofds overheating and burning of the "'/WaX/sincethemelted Wax in proximity to lthe/tube tends to flow outwardly towardthe walls of the potwhere itis cooled, the radiation of heat from thewalls lofthe wax potedectually preventing't-he wax from becomingoverheated at all times. Preferably,- and as illustrated in the drawing,the steam ,pipe,f9 passes through atube 12, the lower end 'ofwhic'l'issecured in the bottom of the .waxpot' and the upperzend of which eX-tends above thedevel ofthe wax and' is receivedin a recess in the''lowerjsurfaee of the 'support 3. Thus tube 12 prevents th Waxf-romconing directly into 'contact ysteam' pipe and avoids calring ofv thewax on f sthepipe. The tube LQ/lcosely surrounds'the 1th the 1 {p1pe' 9so as-'to provide -aniair space.' which aids in preventing overheatingof the Wax. Also the steam pipe 9 is preferably made of copper' Whilethe tube 12 is made of iron, for the reason that the conductivity ofiron is less than that of copper and the iron serves to still furtherdiminish the dangerof eX- cess heating of the Wax particularly at pointsWhere the tube 12 may accidentally come in contact with the pipe.

. While the Waxing device is in use the Wax in the pot is kept melted bythe steam pipe 9. To enable the Wax to be quickly melted When heat isfirst applied to the pot, an auxiliary heating device may be employed.In the construction illustrated in the drawing an auxiliary heating,device in the form of a. steam pipe 13 is provided arranged parallel tothe pipe 9 and connected in the same manner to the supply and returnpipes 10 and 11. This pipe passes through a tube 14 similar in allrespects to the tube 12. Near its loWer `end and outside of the Wax pot,the pipe 13 is provided With a valvel by means of Which communicationYmay bel shut off betWeen'tlie pipe 13V andftlieffpile 11. -When thevalve'l'f/'is'closed Water ofy condensation collects in the pipe 18 andthus ythe operation of the pipe as a heating de"- vice is discontinuedThe loWegf/end of the guide frameYS is provided With lateralprojectio-ns 16 Which fit quite closely. against the tubes 12 and 14 sothat the heat is`trans, mitted directly from these tubes to the' guideframe 8 and thread guide 7.

The preferred embodiment offtlef several features of the presentinvention having been thus described, What isfclai1ned is 1. A threadWaxing device,y having, in combination, a. support, f" a thread guidemounted thereon, a Wazepot mounted so as to be movable into or out of aposition in which the thread is immersed in the Wax, and a heating pipepassing through the Waxpot in a straight line and in the direction ofthe movement of the pot.

2. A thread Waxing device, having, in combination, a support, a threadguide mounted thereon, a Wax-pot, -a heat-ing. pipe passing verticallyin a straight line through the Wax-pot and means for supporting theWax-pot so as to allow it to be moved`longitudinally of the heating pipeinto and outof a position in which the thread is im? mersed in the Wax.

8. A thread Waxing device, having, in combination, a Wax-pot, a heatingpipe passing through the Wax-pot and emerging therefrom below the levelof' the Wax, a thread guide to guide the thread through the Wax in theWax-pot, and a tube loosely' surrounding the heating pipe and attachedto the pot at the point Where the heating pipe emerges therefrom.'

4. A thread Waxing device, having, in combination, a support, a threadguide mounted thereon, a Wax-pot, a heating pipe passing vertically in astraight line through AtheWaX-pot, a tube loosely Ysurrounding theheating pipe and attached at its loWer end to the bottom of the pot, theupper end of said tube extending above the level of the Wax, and meansfor supporting the Wavpot so as to permit it to be moved longitudinallyofl theV heating pipe into or out of a position/fin Which the thread isimmersed in the'WaX.
